Featured Profile: Shubhra Gangopadhyay
Dr. Shubhra Gangopadhyay believes every little bit helps.
Gangopadhyay works with materials that are measured by the nanometer: a unit of measurement equaling one billionth of a meter. Her research involves taking underutilized technologies and using them to develop nanotechnology applications. For example, the nanoscale gratings found inside HD-DVDs and Blu-ray discs have vastly more potential than as simple data storage devices. Gangopadhyay uses these discs as a mold to inexpensively fabricate highly selective and sensitive sensors that can be used to find medical biomarkers.
Currently, Gangopadhyay is developing a smartphone-based sensor system that can quickly quantify cortisol concentration in saliva to evaluate a patient’s stress levels as well as detect disease biomarkers, such as the bacterium behind tuberculosis. This portable system could be used in lower-resourced areas to quickly and accurately diagnose patients for a range of ailments. The nanoscale gratings can also be used in high-tech laboratories to expand the detection limits of current sensors to unprecedented levels.
Dr. Shubhra Gangopadhyay is the C.W. LaPierre Endowed Chair in the Electrical and Computer Engineering Department in MU’s College of Engineering as well as director of the MU Center for Nano/Micro Systems and Nanotechnology.
